I built a TikTok-style shopping feed with a recommender system — in pure client-side JS

TL;DR: I built ThodaSa — a reels-style impulse-shopping demo for the Indian market. You scroll products like Instagram reels, and the feed learns your taste — with no backend, no login, and no tracking servers. The whole recommender is ~150 lines of client-side JavaScript. Code is on GitHub. The idea Quick-commerce apps in India (Blinkit, Zepto, Meesho) figured out something interestin...

Cura doesn't have connector generation. I built a plugin, and a one-click installer, that does.

OrcaSlicer and PrusaSlicer both let you generate mechanical connectors, plugs, dowels, snaps, dovetails, when you split a model for multi-part printing. Cura doesn't, and it doesn't expose an official plugin API you can hook into to add this the right way either. That gap is why cura-connect exists. How I built it Two phases, verified at each step rather than assumed to work: Phase 1...

Sharing memory between processes with java.lang.foreign and jextract

Java Foreign Function and Memory API (java.lang.foreign) is a powerful tool that you can use to take advantage of various OS-specific optimizations. Often though, due to high usage of the C/C++ preprocessor and its powerful macros it can be cumbersome to write and maintain the Java-side code. Help is available in the form of jextract - a JDK tool that reads C/C++ header files (*.h) and gen...

Build a TikTok Hashtag and Creator Research Pipeline in Node.js

A useful trend-research workflow rarely ends with a hashtag count. You usually need to move from a hashtag to recent public videos, then to the creators behind those videos—without silently accepting duplicate pages or anti-bot responses as real data. This tutorial builds that workflow with four read-only endpoints: /v1/hashtag/info /v1/hashtag/videos /v1/users/info /v1/videos The examples us...

OpenWA: A Self-Hosted WhatsApp API Gateway Built for Production

OpenWA: A Self-Hosted WhatsApp API Gateway Built for Production WhatsApp's official API is powerful, but it comes with strings attached: vendor lock-in, per-message pricing, and a closed ecosystem. For developers who want full control over their messaging infrastructure, the alternatives have historically been thin. OpenWA aims to change that. It's a free, open-source, self-hosted Whats...

[260817~0822] 그래픽카드를 바꾼 뒤, 검증 도구들의 허점을 연달아 잡았다

하드웨어 교체 판정이 한 주 동안 두 번 뒤집혔고, 자동 검증 도구 두 개가 조용히 오류를 놓치고 있었다는 게 드러났고, 실계좌에서는 사람이 두 번 직접 개입해야 했습니다 지난 개발일지 이후로 조금 뜸했는데, 그 사이가 오히려 가장 바빴던 한 주였습니다. 월요일엔 그래픽카드를 통째로 바꿨고, 그 판정이 며칠 사이 두 번 뒤집혔습니다. 같은 주에 새로 만든 검증 도구 두 개가 그동안 못 보고 지나치던 문제들을 잇달아 드러냈습니다. 그리고 실계좌에서는 사람이 두 번 직접 개입해야 하는 일이 있었습니다. 그래픽카드를 바꾸고, 판정이 두 번 뒤집혔다 월요일에 그래픽카드를 다른 브랜드 제품으로 교체했습니다. 계산 방식도 함께 바뀌는 큰 작업이었습니다. 화요일에 새 설정으로 정식 배포했는데,...

Stop Guessing Which Model Is Better: Amazon Bedrock Model Evaluation Hands-On

"Which model should we use?" is the most common question in every Bedrock project — and most teams answer it by eyeballing a few responses. That doesn't scale, it isn't reproducible, and it silently expires every time a new model version ships. In this hands-on, we'll answer the question with data: Amazon Bedrock Model Evaluation, run in two modes — automatic metrics scored against reference answ...

Checking whether an npm package "exists" stopped working

Every npm supply chain postmortem ends with the same advice: verify the package before you install it. So I looked at what the tools that do this actually check. Most of them check whether the package exists. That check is dead. Here are three package names documented as AI hallucinations, against the npm registry right now: react-codeshift HTTP 200 react-fetch-hook HTTP 200 unused-imports...

How to Get the Parent Domain from a Cross-Origin Iframe in JavaScript (Without Losing Your Sanity)

1. Introduction If you are developing an iframe-based widget, embedded tool, or third-party script, you will inevitably run into a question that sounds deceptively simple: "Which website embedded my iframe?" Knowing the parent domain is essential for domain authorization, analytics, and security origin checks. But here is the catch: modern web browsers trust nobody — especially not ...
